The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote forecast. According to the model, Clinton will collect 43.8% of the two-party vote share in South Carolina, whereas Trump will end up with 56.2%. In comparison, on October 22, Clinton was predicted to win only 43.8% of the vote.
Putting the results in context
Individual models can incorporate substantial biases, which is why they should be interpreted with caution. Instead of trusting the results from single models, you should look at combined models or, even better, a combined forecast that incorporates different methods and data.
